1253 <p>
1254 </p><h2>September 21, 1999</h2>
1255 <p>There appear to be two new files on the ftp site, <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaLib-3.1beta3.tar.gz">MesaLib-3.1beta3.tar.gz</a>
1256 and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,
1257 that seem to be... yes, I've just received confirmation from the beta center, they
1258 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1259 Keith Whitwell for preparing these for us during Brian's absence.</p>

1261 </p><h2>August 30, 1999</h2>
1262 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1263 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1264 <p>I've been working on Mesa in my spare time for over five years. With Precision
1265 Insight I now have the opportunity to devote my full attention to advancing Mesa
1266 and OpenGL on Linux.</p>
1267 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1268 my work will continue to be open sourced and available to any other programmers who
1269 may want to contribute to it, or use it for other projects or platforms</p>
1270 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>
1271 <p>
1272 </p><h2>August 23, 1999</h2>
1273 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1274 Note that this is a new archive, so you will need to re-checkout the archive. That
1275 means don't <i>cvs update</i> from a previous download.</p>
1276 <p>
1277 </p><h2>August 17, 1999</h2>
1278 <p>A report from the SIGGRAPH '99 Linux/OpenGL
1279 BOF meeting is now available.</p>

1283 <p>www.mesa3d.org is having technical problems due to hardware failures at VA Linux
1284 systems. The Mac pages, ftp, and CVS services aren't fully restored yet. Please be
1285 patient.</p>

1297 <p>Beta 2 of Mesa 3.1 has been make available at <a href="ftp://ftp.mesa3d.org/mesa/beta/">ftp://ftp.mesa3d.org/mesa/beta/</a>.
1298 If you are into the quake scene, you may want to try this out, as it contains some
1299 optimizations specifically in the Q3A rendering path.
1300 <p>
1301 </p><h2>May 13, 1999</h2>
1302 <p>For those interested in the integration of Mesa into XFree86 4.0, Precision Insight

1305 </p><h2>May 13, 1999</h2>
1306 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1307 US$10,000 to the Mesa project to support its continuing development.
1308 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1309 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1310
1311 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1312 improve performance on 3d hardware.  Thanks to Keith's work, many
1313 applications using Mesa 3.1 will see a dramatic performance increase
1314 over Mesa 3.0.  The donation will allow Keith to continue working on
1315 Mesa full time for some time to come.
1316
1317 For more information about Mesa see www.mesa3d.org.  For more
1318 information about id Software, Inc. see www.idsoftware.com.

1322 This donation from John/id is very generous.  Keith and I are very
1323 grateful.
